Turbosmart GenV RacePort Blow Off Valve – Blue

The Turbosmart RacePort is famous for being an amazingly small and light BOV for turbocharged competition level engines. Featuring our unique collar design and internal flow structures, it is 50% lighter and 25% smaller than the competition while flowing 330 CFM – making it the highest flowing BOV of its type on the market.

SUPPLIED WITH:
GenV Raceport 50mm BOV
1/8 NPT Vacuum fittings
V-band Assembly
Profiled Alloy Weld-On Fitting
Blue Spring Rated -18 to -14 InHg (installed).
Turbosmart Decal
How much boost can this take?
How much do you have? We’ve not found a limit on an actual vehicle & this is confirmed on Competition & Record Holding Pro-Mod & Diesel Race Engines reaching for 120psi / Over 8 Bar Boost. The limit is far higher than that – Proven.
OK, so what is the limit of this valve?
The valve is capable of bypassing ~2500HP worth of airflow – meaning it can bypass about 2500HP, and seal against 2500HP when required. It won’t fail or let you down if you exceed that, but you may experience some compressor surge.
What if I’m expecting over 2500 HP?
We have 2 options for you! Firstly, you could simply run an additional GenV RacePort or secondly, investigate Turbosmart’s PowerPort range for up to 3000HP worth of bypass flow capability.
Why Turbosmart RacePort?
Turbosmart sets the bar for flow and footprint! We’re talking 50% lighter, and 25% smaller than the competition. Designed with a specialized diaphragm system unique to Turbosmart, the Race Port is the fastest responding valve on the market. You could say it’s engineered to win.
What Fittings Does it use?
The Gen-V Race Port BOV range, like all Gen-V products, is supplied with 1/8th NPT ports and simple hose connection barbs supplied in the box.
Can I upgrade to a Sensor Cap?
Yes! If you already own a GenV RacePort, there are upgrade kits available in either blue or black. If you haven’t yet made your purchase, the GenV RacePort range offers the RacePort with Sensor Cap pre-installed as an off the shelf item. Note that the GenV Sensor Cap upgrade kits are specific to the GenV range, and will not suit Gen 4 or earlier versions of the RacePort.
I have a supercharger – the GenV RacePort suited to my application?
Yes! The Gen-V Range includes a supercharger specific version that is fitted with a soft spring designed to operate with supercharged systems. If you already have a standard Race Port, the softer supercharger spring is available as a spare.
Does the GenV RacePort fit ‘other’ 50mm flanges?
Yes, if you look through the range of GenV RacePort BOV’s from Turbosmart you’ll see some of them refer to ‘Female Flange’ & this is what you’re after – there’s a special part number, just for that!
